Sound therapies are a common component of treatments for tinnitus and hyperacusis. The original idea was to partially or completely mask tinnitus with broadband noise delivered by sound generators or hearing aids, for a few hours each day. Over several months, many patients reported that their tinnitus became quieter or easier to bear, and that loud sounds became less aversive. However, it wasn't always clear that these benefits could be attributed to sound therapy rather than to other aspects of treatment, such as counseling or hearing aid use, and not all patients reported benefits. During the past few decades, many other sound stimuli have been tried, including tones, noise bands, music, and nature sounds. These sounds have been filtered in relation to the tinnitus pitch, adjusted for hearing loss, amplitude-modulated, and recently paired with electrical nerve stimulation. Many of our ideas about the neural underpinnings of tinnitus and hyperacusis come from animal models. However, studies of sound treatments in animals with putative tinnitus or hyperacusis have been rare. Clinical sound therapy trials are emerging, but outcomes typically remain modest, and few patients achieve complete remission of tinnitus or hyperacusis, unless the underlying hearing loss is treated with hearing aids or implants, in which case success rates are higher. More studies are needed, on both animal models and human subjects, to further explore the rationales for the various sound therapy options reviewed here, and to optimally tailor sounds and treatment approaches to individual patients, so that maximum benefits can be obtained.

A nonspecific symptom of hearing disorder characterized by the sensation of buzzing, ringing, clicking, pulsations, and other noises in the ear. Objective tinnitus refers to noises generated from within the ear or adjacent structures that can be heard by other individuals. The term subjective tinnitus is used when the sound is audible only to the affected individual. Tinnitus may occur as a manifestation of COCHLEAR DISEASES; VESTIBULOCOCHLEAR NERVE DISEASES; INTRACRANIAL HYPERTENSION; CRANIOCEREBRAL TRAUMA; and other conditions.
Therapies using arts or directed at the senses.
The transmission and reproduction of transient images of fixed or moving objects. An electronic system of transmitting such images together with sound over a wire or through space by apparatus that converts light and sound into electrical waves and reconverts them into visible light rays and audible sound. (From Webster, 3rd ed)
Ability to determine the specific location of a sound source.
Prenatal interventions to correct fetal anomalies or treat FETAL DISEASES in utero. Fetal therapies include several major areas, such as open surgery; FETOSCOPY; pharmacological therapy; INTRAUTERINE TRANSFUSION; STEM CELL TRANSPLANTATION; and GENE THERAPY.
Hearing, auditory perception, or audition is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. Sound may be heard through solid, liquid, or gaseous mat...
